Either I misunderstood previous messages or something is still wrong.

One message said: always unit address, so there will be no
fpga-bridge-1. This means "?" is not correct.

Other message was saying "reg" is not required in one of the bindings,
thus "fpga-bridge-1" is reasonable if there are more than one bridge
(which was already said as possibility?).

Best regards,
Krzysztof
